Speccation of Letters Patent.

Patented oct. 15, 191s.

Application filed August 3, 1917. Serial N o. 184,186.

To all 'whom it may concern.'

Be it known that I, GEORGE W.- MANNING, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have in-vented certain new and useful Improvements in Broom-Making Machines, of which the following` is a specification, reference being had to the accompanying drawings.

My invention relates to broom making machines ofthe general type shown in Letters Patent granted to me on February 18, 1913, No. 1,053,192. It is one of the objects of my-invention t-o provide in a machineof this general type means for pushing or otherwise clearing the broom corn or other broom material from between the handle portions of the clamps so as to provide free and easy entrance for the handle when the broom is completed. V.It Fis another object of my inventionlto provide means for clearing the broom material away in this Amanner after the clamps have been partially pressed together but before the complete pressure is applied tothe clamps. It is anotherrobject of my invention to provide for driving in the earsat the sides of the'clamps both before and after the pressing operation, the broom material being thus firmly gripped between the ears and the clench pins or other devices Afor securing the clamps together in compressingposition. It is another object ofmy invention to provide an improved form of supporting and spacing means adapted to coperate "with the rotary table for holding the bundles of broom material in proper position for receiving the clamps.

It is another object of my invention to pro' vide means for feeding the clamps properly into position in the chucks, this being pref erably accomplished automatically in proper timed relation to the other operations of the machine. Itis another object of my invention to provide means 'for applying clench pins and properly fastening them in position for securing the clamps together in lieu of the rivetsheretofore employed. It is another object of my mvention to provide new and improved means for feeding the'clench i pins or other fastening` devices, wherebv the delivery 0f the fasteningA devices is prevented when at any time a chuck passes the fastening point without a bundle of broom mag terial in position thereonbetween its accompanying clamps. It is another object of my .invention to provide improved meansholding the pivotally mounted chucks yieldingly 1n raised position. It is another ob- ]ect of my invention to provide improved means for closing the pivotally mounted chuck with the clamp carried thereby down upon the bundle of broom material preparatory for the compressing operation. Itis still another object of my invention to improve mechanisms of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated inthe drawings and are hereinafter specifically described. That which I believe to be new anddesire to cover by this' application is set forth in the claims.

Fig. l2 is a vertical cross-section through the means for delivering thel clamps 'from av stack and-pushing them into positionupon the vertically-'positioned lpivotally mounted chuck; and i 'Figg 13 is-.a vievv'showing the arrangement of the sli'defplates in connection Wit-h a hop-` pe'rfor delivering rivets or clench pinsl to theclamps.

yReferring tothe l several figures of the drawings, in Which corresponding parts` are indicated byy the" same reference characters-e 2(7)V indicates "a column rising from a base 215, having a table orv carrier 22 revolubly mounted thereon. The table 22 is provided With a plurality'of horizontally-disposed chucks 23 each adaptedtoreceive in positionA thereon a broom clamp 24,1as shown atwthe right in Fig. l". Pivotally mounted adjacent to each ofthe horizontally-disposed chucks 23 is a coperating chuck 25 each of whichA isadapted t'o have anappropriateclamp 26 delivered thereto, as is best shown in Fig. 12.

Means is` provided for rotating thetable 2,2 intermittently step by step. VAsY each of the chucks 23 comesinto the position di rectly at the yright in Fig, l, an operator placesa bundle 'of broom material 27 inposition upon the clamp'24 and promptly closesv theV chuck 25 with the clamp 26 therein down uponA the bundle. This is effectedv preferably by means of a Jfoot lever 28 pivotally mounted upon Lthe column 2O connected at its inner end by means of a link 2 9 'with `a bell-crank lever 30, the vertically extending arm of Which is connected With a punch' or ram 31 which is moved outward for forcing the chuck 25 down upon an appropriate down- Ward movement ofthe lever 28 against the action of the spring"32.' TheN chuck 25 is normally held in raised position by means of a catch device 33 mounted upon the" chuck 25 in engagement With a'catch device 34 carried by the chuck 23, the catch devices 3 3-34 being adapted to yield suiliciently to permit ofa yielding'engagement and disengagement. l A

Al\`/[e"ans isv provided 'for supporting; the outer ends of the'bundle's 27 as they are placed successively in position upon the chucks 23 inI the movement of the'v table`22.,

This meansv islillustratedat oneportion of thef showing of Fig; 1. It will be understood that this-supporting means in practicev extendsclear about'the tablef22', but is omit-A ted for clearness ofillust`ration. lThis supporting means' comprises arms 35 extending outvvard from the table'22'Y` supporting an chuck closed ldown-upon the-bundle asvsliown attheright-'in F igl', .this chuck cornes to the point Where pressure isl applied for' com# pressing the clamps upon the bundle of broom material. Pressure is applied tothe uppermost chuck 25 by'means ofY a pressure head 39 mounted upon the lower end-E of' aram; 40'vvhich. is Vslidably mount-edi in suitable brackets 41442? extendinglaterally 40 has pressure applied theretofbyg means of a collar 43 which i's1connected\5 by means of toggle arms'4`4"'45' With thebrackettl'. The joint ofthetogglefarms is connected by a vlink 46 `With the vertically-ei'- tending arm of abell-crank lever47g\ theot-he'r' arm' offvvliic'h` is connected byl meansof a link 48 With any suitable powerdevice Which` is actuated in timedf relation to the motion of the rotary V table! for moving the pressurehead 39 downward; as is' desired. The Vlink 48 isfpreferably actuated by afsuit'- vable cam mechanism linthe manner' fully' illustrated' in my patent aboveV 'referredi to.Vv When the rupjrermost Achucks 25 f havebeenl moved' downwardto the liifnitl oftheir motion. they are held in'comp'ressingposition` by means of spring latch devices 495 asis best-shown in Figs; 3' and` 4. When the" pressure head 39 has made a partial downwardstroke,` a ram` 50 isl'inoved outward through a suitable opening in the side of the column 20 (see Fig; 9)- foi-push-v ing the partially compressed broom-materialv outof the handle portions vof the clamps-24'-A 26. As is best shovvnin Fig. '10, the ram 50 is builtv up ofa plurality of separate` parts. whereby its size and shape may be regulated to suit the thickness' of'broom beingmanufactured. As is bestl shown "in Fig. '9; t-he ram 50 isoperated by means' of a link 51-Y connected with one'end cfa bell-crank lever 52, the otherend ofvvhi'chV has a verticallyslidable connection vv-ithl the -ramO'by means .of'a slide-box 53 thereon. Theilink 5`1i`s adapted to -be operatedby any suitable povve'i` mechanism in tiined relation vtot the action of the pressure head1 39,V so asto have itsV action after the bundle'of broom material is partially compressedl and before: thel entire pressure has beenv applied; Y Means is provided at `the plessurestationof the machine for' driving in the'ears 54 carried at opposite sides of the clamps 24-26, in substantially the manner illustrated in my said patent. This means comprises rams or punches 55 mounted at the sides of the pressure head 39 which are adapted to force inward the slide-blocks 56, the inner ends of which engage the ears 54, as s best shown in Fig. 5. The rams 55 in their downward movement engage also pressure blocks 57 ixed in appropriate position upon the table 22, as is 'best shown in Fig. 1.

When the pressure has been applied to the chucks as just described, the chucks are next moved to the riveting station of the machine. driving h eadr 58 is slidably mounted in a bracket 59 extending outward from the column in position to permit the compressed chucks toi-pass under. The driving head 58 is connected by means of bolts 60 -with acrosshead 61 Vmounted upon the lower end of a punch or ram 62 which is slida'bly mounted in a bracket 63 extending from the column 20. Heavy coiled springs 64 are inserted upon the bolts 60 between the crcsshead 61 and the driving head 58 serving to hold the driving head yieldingly downward relative to the crosshead 61 (see Fig. 4 for this construction). The driving head is provided 'with tubes 65 which have telescopic connection with other tubes 66 (see Fig. 7) for delivery of rivets or pins from a suitable source to the driving head 58, such tubes corresponding in number and position with the number of'openings through theclamps for receiving such pins for securing the clamps together about the bundle of broom material. In Fig-7 a pin 67 is shown in position in a suitable socket 68 in the driving head 58 ready to be driven through the openings of the clamps upon the descent of the rams 69 as hereinafter described. The pins or rivets 67 are held yieldingly in position by means of slide-blocks 70 pressed yieldingly'toward each other by means of suitable springs 7l.'

Fig.^5 illustrates two of the rams 69 driving suitable pins 67 into position, showing the lower ends of the pins being clenched or turned backward into the body of broom material by means ot suitably shaped' dies 72 carriedby the lower chuck member 23.

As is best shown in Fig. 7, vthe rams 69 are fixedly mounted in the crosshead 61 and are adapted to descend therewith. The crosshead 61 and the ram 62 are adapted to be moved downward by means of togglearms 73--74 connected with the Ibracket 63 and the ram 62, respectively, the toggle joint being connected by means of a link 75 with one 'arm of a bell-crank lever 76, the other arm of which is connected by means of a link 77 with any suitable source of power adapted te actuatev such linkin proper timed relatio-n, as' is readily understood. The link 77 is also provided with a collar 78which at substantially 'the end of the downward movement of the link is'adapted to engage one end of a lever 79 for bringing the other end of said lever` upward into contact with the dies 72 for giving said dies a slight upward movement for nishing the complete clenchiug of the pins 67. The crosshead 61 is also provided with rams 80 at opposite sides thereof adapted to be brought` down between th'e stationary blocks 57 and the slideblocks 56 for giving the ears 54 of the clamps a supplemental drive inward toward the pins 67 so as to clamp the broom material between the ears and the pins very firmly in position. Supports 81-82 for the table 22 are provided at the compressing station and the pin driving station so as toi relieve the table from undue strain at these points.

The means for delivering clench pins'to the driving head 58 comprises a hopper 83 (see Fig. 13), which is pivotally mounted in suitable position and is preferably adapted to be rocked at intervals, as is described in my said patent. The pins` 67 are fed to the tubes 66 by means of two slideplates 84-85 of the type illustrated in my patent. As is best shown in Fig. 6, the slide-plates 84-85 are adapted to be moved relative to each other by means of two plungers 86-87 which work in suitable openings in said plates. The plunger 86 is connected with an arm 87a extending from the cross-head 61, the plunger 86 being given a positive up and down movement with said crosshead. The plunger 87 in turn is connected by means of a link 88A with an arm 89 -which is adapted to be swung up and down about a shaft 90 as an 'axis by means of an arm 91 which is adapted to be engaged by a bundle of broom material on the chuck in compressing position. When there is va broom in position in each of the chucks as it arrives at the compressing position, the plunger 87 is moved upward by the upward movement of the arm 91 actuated by the bundle of broom material. When, however, a chuck arrives at the compressing position Without a bundle of broom material in position thereon, the arm. 91 remains in lowered position and the upward movement of the plunger 86 accordingly has no effect upon the plates 84-85 whereby no clench pins are delivered. It will be understood that whether or not the plunger 87 is moved upward into the position shown in Fig. 6, the plunger 86 makes its periodical upward movements regularly with the crosshead 61. In case the link 88 is moved upward after the plunger 86 has moved upward in advance thereof, the plunger 87 is prevented i from moving Y upward byreason of thev play provided by the spring 92 interposed in the connections between `the link 88 and the plunger 87,

thezspring 92 f being strong 'enough to raise thev plunger 87 -when the plunger 86 vis in its lowered. position,A but being of insufficient strength to raise the plunger 87 when the plungerv 86has risen in advance. y

`After the;v completion of the broom at the clenchingstationas ,jjust described, the further movement of the table serves in any suitable manner to release the chuck 25 from the latch devices 49, the chuck 25 being then raised to its open position by means of a plunger 93 carried vby an arm 94 extendingffro-mptheram- 62 (see Fig. 4.) As is bestl shown inFig. 8, the plunger 93 engages the lat-ch deviceA 33 of the chuck 25 and by downward pressure thereon raises such chuck, the latch device 33'being moved by this operation into engagement with the latch device 34. Guides or guards 95-96 are provided for preventing possible misdirection of the plunger 93, and a spring 97 is also provided for assisting in the proper control .of the plunger 93.

` Coming now to vthe means Afor delivering the clampsj tothe chucks, 98 indicates a housing adapted to hold a stack of clamps 24e-(Seel Fig. .11).= 99 indicates a plunger slidablyjmounted upon the bracket 100 supporting the housing 98, the inner end of said plunger being opposite the lower-V most one .of the clamps 24 of the stack supported in said housing. The plunger 99 is provided Vnear its outer.V end-with a stud or roller 101 which is adapted to be engaged by a diagonally-'disposed slot 102 in a block 103 which isadapted to be moved upward in suitable timed relation for causing an inward movement of the plunger 99 for pushing 'the' lowermost clamp 24 toward the leftin said Fig. 11 "so as to drop into position upon the chuck 23.v The block 103' is movedupward by. means of a rod 104 which is given the desired movement by any suitable'mechanismv in the proper timed relation.

105indicatesahousing adapted to receive a stack ot' the clamps 26 (see Fig. 12). A plunger '106' slidably mounted upon the housing 105 lhas its end portion in engagement with the lowermost clamp 26 so as to be adapted to push said lowermost clamp toward: the right in Fig. 12 for delivery. The plunger'106 is operated in the construction shown by meansroi' a lever 107 (see Fig. .9) which in turn .is actuated by lugs 108 'carried'by theram50. The plate 26 delivered from thebotton'i of the stack in the housing 105 as above described is received into z a vpocket formed by plates 109-110 which are spaced apart with .a yplate 111 between them at their lower edges, the plate 111 being of ashape to correspond to that olfl the clamp 26, whereby the clamp is supported evenly in position upon the plate 111 when it falls intoy position thereon. The

. plate 110. is provided with an `opening .correspondingto the outlineY ofy the clamp-2650 as to permit'free movement of the .clamp therethrough. Springs 112 are provided invsuitable position for engagingthesides ofthe handle portion of the clamp in position upon the plate 111. A cro'sshead 113 is movably mounted in suitable position relative to the housing 105, in the construction shown being supportedlby means of slidably mounted pins orv plungers 114l whichv are xedly connected with said crosshead. The plungers 114 are providedr at vtheir end portions with pins 115 which are adapted to enter suitable openings in the clamps 26 upon a suitable movement of the crosshead 113 toward the left in said Fig. 12. As will be readily understood, when the crosshead 113 is moved toward the left to: bring the pins 115 into engagement with the openings of the clamp 26, a further. movement-of the crosshead toward the left in said figure will serve to move the clamp toward the left between the springs 112, serving to carry the clamp into positionupon the chuck 25. In the'construction shown, thecrosshead 113is given an operative `movement toward the leftv in Fig. 12 by meansof a leverY 116operated from the ram 99 and a second lever 117 connected with' the lever 1.16 and with the crosshead 113.

Asis best shown inFigs. 11 and 12, both of the chucks 23-and 25are. provided with suitable pins 118 adapted to engage the edges of the clamps-so as to vholdftheclamps in suitable position thereon. A- support 119 of any suitable type is providedadjacentto the-chuck 25 at the'pointwhere the clamp 26 ispressed by the rods 114 into position on said chuck. c f What I' claim` as myy invention andl desire to secure byl Letters Patent, is:
